'ro -ALL WHOM4 1T MAY CONCERN:

Be it known that I, THOMAS W. MURRAY, of the city, county, and State ofNew York, have invented a ln'cWand imp'ioved.l Device for'Operating theRudders of Vessels; and that the following description, taken inconnection with the accompanying drawings, hereinafter referred to,forms a fulland ex'act specification of the same, wherein I llave setforth the nature and principles of my said improvement, by which myinvention may be distinguished from all others of a similar class,together with suchparts as I claim, and desire to have secured byLetters Patent. I

This-invention consists in constructing the rudder of two pieces, thelower part forming the blade, being somewhat similar to the lower partof the rudder now in use, but the upper portion or post isentirely-dissimilar, being constructed independently of the blade, andVis composed of a shaft of iron orother metal, bent in the form of acrank, and is connected with the blade atits outer edge instead of theinner.

The objects of the invention are to control the blade of the rudder atapoint situated at its outer edge, or at 'the circumference of thecircle, instead of at the centre; to prevent the bending and twistingoff of the post, which is so frequent an occurrence with the ordinaryrudpders now in use; to keep the metal post free `from immersion inwater, by placing the saine entirely above the waterline. In theaccompanying sheet of drawings- 'Figure 1 is a side view of myinvention, applied to a vessel, partly in section.

Figure l is a'plane view of the post or shaft, showing its connectionwith the blade and stern-post.

A representsI the post or shaft, bent in the form of a crank, and iscomposed of ironeor other metal. vB4

is a metal band or strap, holding the post A in position. In the latterthere is turned a. recess or groove, into which the band ts, therebypreventing the post from rising or falling. C is the blade of therudder, which is of wood orirOn, as may be the case with the vessel. Dis the stern-post, on which the band B is rmly bolted, and the blade Chung. E is a. vertical pin, firmly secured to the outer edgevof thebladeC, and fitting into a. corresponding hole made in the outerextremity of the post A. The pin E should be jacketed with rubber.1 to

`relieve in a `tneasLue the sudden strain on it and the post, caused byheavy seas striking the blade, as well as to prevent the constant rattlethat would ensue, should the metal pin and post be directly in contact.

By theiise of this device, it is believed that the frequent loss of anddamage to vessels, occasioned by the twisting oit" of the rudder-postsno w used, will be prevented.

Having thus described my invention, I claim as new, and desire tosecureby Letters Patent- '.lhe shaft A, formed with a crank u pon its lowerend, when used in combination with the rudder-blade C,

to which it is connected at its outer edge by means of a pin or pivot,substantially as and for the purpose herein set forth. A
